  1. Note: P 1 value: comparison of data among Hepple MRI Grade groups for AOFAS score of pre-treatment and post-treatment. P 2 value: comparison of data between trauma group and no trauma group for AOFAS score of pre-treatment and post-treatment. P 3 value: comparison of data by trauma history and MRI grade for peri-treatment AOFAS score variation.
